CORROSION INHIBITORS – Boiler Systems (Amines & Oxygen
DEAE (Diethylaminoethanol) / DEEA (Diethylethanolamine) – DEAE is a chemical product that has neutralizing and oxygen scavenging characteristics, and is used as a corrosion inhibitor for steam and condensate lines. As an alkanolamine, it maintains a constant alkalinity in boiler water and condensate, and it does not contribute solids to the boiler system.
Diethylaminoethanol (DEAE) is a clear liquid. It is used as a neutralizing amine for boiler water, coatings, etc. Diethylaminoethanol (DEAE) is used as neutralizing agent and CO 2 scavenger in boiler water. The ideal vapor pressure and vapor-liquid distribution properties of DEAE make it the best choice for pH adjustment of process water.
